I have a relatively simple function that passes in a double. If I pass
in perl's 'undef' value, perl crashes. I assume that's a memory access
problem with perl? Is there a way around this? I don't want to check
the argument value on every call and I can't change the called code.
Pl. advise. Thanks.
